Hi guys

Something has broken hoping you can help...
I have a Dell 24" monitor connected to a HD7850 via DVI. I turned on the PC last night and there were green lines patches over the startup screen and then the windows boot screen. I then wasn't able to get to the windows login screen (i think it's blue screening but I can't see it). I was able to boot into safe mode and login to windows (still with weird lines on the screen) but following this could still not boot into windows. I've managed to uninstall the AMD drivers etc. but still no effect.

Upon removing the graphics card I hooked up my TV to the HDMI port on the motherboard - all working fine. Put the graphics card back in - same problem still there. I'm also unable to get any output from the HDMI port on the graphics card (can't see the bios startup screen for example).

Unfortunately this stupid motherboard only has HDMI out so I can't test my monitor hooked up to the motherboard to rule that out. I will try hooking the monitor up to another PC tomorrow and also try putting another graphics card into the PCI-E slot to see if that works.

Is there any other diagnostics I need to do before conceding it's the graphics card that's died i.e. could it be a memory problem?

Will attach pics, thanks for your help.

So I've tried my brothers 290 in my PC today and it works fine (using same monitor and DVI cable). Anything else to rule out or is it definitely the card?
 
If another GPU works with your remaining components and monitor, then I am afraid the odds are that your own GPU has had it's day.

From your screenshots it looks like VRAM is the likely culprit. Is the card still under warranty?

Oh well :( thought as much.

I purchased it on 10/9/12 so it's a month out of warranty sadly (although I think Gigabyte go on the manufacture date so probably more than a month)

Looks like it's between the GTX 970 vs R9 390 for a replacement...
 
you could maybe fix it by turning down the memory speed, i have an 8800gtx still going strong at about 150mhz less and counting on the memory, will at least tide you over until you decide on a graphics card

I've tried using afterburner by booting into windows using output from mobo hdmi, but everything says "0" and can't change anything...
If i try and connect anything to the output of the gfx card in standard windows I lose all outputs.

Is there any way to turn down the speed in Safe Mode or outside windows?
 
So I've started looking at 970s....

YOUR BASKET
1 x MSI GeForce GTX 970 Gaming Edition 4096MB GDDR5 PCI-Express Graphics Card £299.99
1 x Gigabyte GeForce GTX 970 G1 Gaming 4096MB GDDR5 PCI-Express Graphics Card £289.99
1 x EVGA GeForce GTX 970 SSC rev2.00 ACX 2.0 4096MB GDDR5 PCI-Express Graphics Card (04G-P4-3975-KR) £289.99
Total : £889.57 (includes shipping : £8.00 Ex.VAT).



I'm actually not sure if the Gigabyte will fit inside my case...also the fact my Windforce went pop 3 weeks outside warrant is a bit disconcerting. The EVGA looks fastest out of the box and can be upgraded to 5yr warranty for £12, tempting...any thoughts?

Have you tried upping the voltage on the core/memory?

Any way I can do that from safe mode?

Also looking at the R9 390 as well...but concerned I'd need a PSU upgrade, I've read of people struggling to run it on a good quality 600w?
